*Defined as time from arterial puncture to last coil detached
†For patients with constructively treated saccular aneurysm
‡For one patient, both balloon and flow-diverter adjunctive techniques were used
§For Penumbra coils only. Thirteen patients are missing re-access information for Penumbra coils.
¶Reported by device (# of kickout occurrences over # of Penumbra coils used)
